June 2, 2021—Lawmakers have asked President Joe Biden for time to review a contract for building the U.S. Postal Service's new fleet of vehicles, in part because so few of the vehicles would be electric.

Cleveland.com reports that Ohio lawmakers from the U.S. House and Senate have asked for review of the $6 billion contract with Wisconsin-based Oshkosh Defense for 165,000 vehicles to make sure "no inappropriate political influence was exerted."

The lawmakers are also highlighting the fact that only 10 percent of the vehicles would be EVs, saying it's out of line with Biden's executive order to move all federal vehicles to having zero emissions.
